• T-S parameters are measured after an exercise period using a preconditioning power test. The measurements are carried out with a velocity-current laser transducer  and will reflect the long term parameters (once the loudspeaker has been working for a short period of time).
  ** The Amax is calculated as (Lyc – Hag)/2 + (Hag/3,5), where Lyc is the voice coil length and Hag is the air gap height.
